: Perlecan is an extracellular matrix proteoglycan suggested to maintain endothelial functions. We aimed to measure maternal serum perlecan levels in different preeclampsia phenotypes.: This study included 50 women with preeclampsia and 30 healthy pregnant women.: Serum perlecan levels were significantly higher (p = 0.016) in preeclamptic women with severe features(n = 23) than preeclampsia patients(n = 27). There were no statistically significant differences in serum perlecan levels between the early-onset preeclampsia(n = 25), late-onset preeclampsia(n = 25), and healthy pregnancies.: Our findings suggest that preeclamptic women with severe features have higher serum perlecan levels than women with preeclampsia.

Preeclampsia (PE) is a pregnancy disorder characterized by hypertension and end-organ damage. Reliable biochemical markers for diagnosis and prediction of PE severity can improve maternal health, and several of these markers have been suggested till now. The goal of our study was to evaluate maternal serum levels of Perlecan and Ischemia modified albumin (IMA) in PE patients, and to investigate their relationship with the severity.

Apoptotic exosome-like vesicles (ApoExos) are a novel type of extracellular vesicle that contribute to the propagation of inflammation at sites of vascular injury when released by dying cells. ApoExos are characterized by the presence of the C-terminal perlecan LG3 fragment and 20S proteasome, and they are produced downstream of caspase-3 activation. In the present study, we assessed the relative roles of autophagy and caspase-3-mediated pathways in controlling the biogenesis and secretion of immunogenic ApoExos.

Atherosclerotic cardiovascular disease causes heart attacks and strokes, which are the leading causes of mortality worldwide. The formation of atherosclerotic plaques is initiated when low-density lipoproteins bind to heparan-sulfate proteoglycans (HSPGs) and become trapped in the subendothelial space of large and medium size arteries, which leads to chronic inflammation and remodelling of the artery wall. A proliferation-inducing ligand (APRIL) is a cytokine that binds to HSPGs, but the physiology of this interaction is largely unknown.
